COMBINATION SOIL-PIPE DRAINAGE AND V'ENTING FITTING.

SPECIFICATION forming part of Letters Patent No. 635,619, dated October24, 1899.

Application filed April 6, 1899. Serial No. 711,990. (No model.) I

To all whom, it may concern:

Be it known that I, FRANK WALKER, a citizen of the United States,residing at Los Angeles, in the county of Los Angeles'and State ofCalifornia, have invented a new and useful Combination Soil-PipeDrainage and Venting Fitting, of which the following is a specification.

One object of my invention is to provide a fitting for use in drainageand venting plumbing of buildings which will combine in one piecemeansfor attaching to the dischargefitting of the basin, bath, or otherfixture to vide means whereby two parallel lines of pipe,-

one of which is used as a soil or drainage pipe and the other one usedas a vent-pipe, may be joined in an inexpensive manner, so that thesoil-pipe is vented into the vent-pipe Without danger of the drainageflowing over the basin or other fixture onto the floor. I accomplishthis by having the upper end of my venting-duct terminate and connectwith the vent-pipe at a point on a level intermediate the top and bottomof the basin or other fixture. Should there be any backflow of waterfrom a stoppage of the drain-pipe, it will run out into the vent-pipebefore rising to the top of basin or other fixture and will show waterin the bottom of basin at the same time, which would indicate a stoppageof drainpipe. WVhileIconsiderthisconstructionpreferable, it is to beunderstood that I do not limit myself to such proportions, but may makethe fitting of any length.

My fitting comprises a soil-pipe member straight throughout, a vent-pipemember straight throughout parallel with the soil-pipe member, and adrainage receiving and venting duct connecting the lower portion of thesoil-pipe member and the npper'portion of the vent-pipe member.

My invention also includes a drainageand venting fitting comprising asoil-pipe mem-' her, a vent-pipe member connected therewith, and adeflector arranged to discharge the drainage downwardly into thesoil-pipe mem-v her.

The accompanying drawings illustrate my invention.

Figure 1 is a view of my combinationsoilpipe drainage and ventingfitting. Fig. 2 shows my invention as it is arranged in the pipe-linesto take drainage from four floors of a building. Fig. 3 is a verticalsection taken through the drainage and vent duct which connects thelower end of the soil-pipe member and the upper part of the vent-pipemember. This view is taken on line 3 3, Fig. 1. Fig. 4 is a horizontalcross-section on line 4 at, Fig. 1. Fig. 5 is a vertical section of thefitting on line 5 5, Fig. 3. Pieces of soil and vent pipes are shown inplace in this view. Fig. 6 is a horizontal cross-section on line 6 6,Fig. 1. Fig-7 is a vertical section of the top fitting, as shown on line7 7, Fig. 2. This view shows inlet-ports and the deflectors arrangedover such ports to direct the flow of water downwardly.

A is a soil-pipe.

B is the vent-pipe.

O is the drainage and vent duct.

0 and c are lateral openings into the drainage and vent duct.

0 G are deflectors arranged above the mouth of the laterals c and c.

E are drainage-laterals from the basin or other fixture.

F is a union coupling, which is formed by cutting a thread J on thelaterally-projecting nipple on the enlarged portion of the drainage andventing duct.

K is a packing-nut.

G is a wiped joint, which is wiped onto a nipple that is screwed intothe lateral opening of the duct.

H is the vent-opening into the vent-pipe, and I is the opening from thedrainage and vent duct 0 into the soil-pipe A.

In the manufacture of my fitting it is cast in one piece, the openingsfor venting and drainage being formed by means of cores. Thedrainage-laterals are arranged to discharge in the lower portion of thedrainagereceiving and venting duct and are provided with the curveddeflecting-plates C and 0 above their mouths. Such deflectors extendforward and downwardly from the wall of the duct slightly into thechannel of the pipe. These curved deflecting-plates prevent the incomingstream from the laterals from cross ing the channel of the pipe anddirect it downward along the wall of the channel upon the side on whichthe opening is located. This prevents any splashing upward of water orthe dammin g which accompanies an infl owing stream of water whenstriking against another in flowing stream of water or when strikingagainst an opposing wall.

It is well known that water carrying soap and grease will deposit thesame when allowed to splatter upward and then drain down slowly. Thishas a tendency, together with the scales that drop off the iron pipe, tostop the vent and in some cases stops the pipe solidly. This does notoccur where a body of swiftly-moving water strikes, and by myconstruction I prevent .any drops of water from getting outside of thetrack of the flow of the full stream.

The drainage receiving and venting du ct is swelled outwardly at thepoint of entrance of the laterals, as shown at d d. This allows thedeflecting-plates to be placed within the body of the drainage andventing duct and allows free egress for the venting of gases, the.

By the use of my fitting in plumbing the soil-pipe is made in onecontinuous line from its lower portion to its top, and the vent-pipe isone continuous straight line from its bottom to its top parallel withthe soil-pipe.

By the use of my fittings I am enabled to drain and vent a building withbut very little cutting away of the partitions, as I do not requireseveral branches or pipes for venting. Nor do I require as wide a spaceto run the pipes as in any former construction.

By the use of my improved fittingI am enabled to drain and vent thedrainage of a building with a less number of joints and fit tings thanwith any other fitting or fittings with which I am acquainted, and I useless pipe and require less labor to install the same.

Now, having described my invention, what I claim as new, and desire tosecure by Letters Patent, is y 1. An integral drainage and ventingfitting comprising two substantially parallel members open throughoutand each adapted at each end to connect with upper and lower pipes, anda connecting member substantially parallel with the said first-namedmembers and opening from the one member at one end of the fitting andinto the other member at the other end of the fitting.

2. A drainage and venting fitting comprising a soil-pipe member straightthroughout; a vent-pipe member straight throughout and parallel withthesoil-pipe member; a drainage receiving and ventingduct connecting at itslower end with the lower part of the soilpipe member and at its upperend with the upper part of the vent-pipe member and also provided nearits lower end with lateral openings to receive the drainage.

3. A drainage and venting fitting comprising a soil-pipe member; avent-pipe member connected therewith; a lateral drainage-dischargearranged to discharge into the drainage and vent pipe member, and aninclined deflector arranged inside of the drainage and vent pipe memberabove and over the lateral drainage-discharge to direct the waterdownwardly.

4:. A drainage and venting fitting comprising a soil-pipe memberstraight throughout; a ven t-pipe member straight throughout parallelwith the soil-pipe member; a vent and drainage duct connecting thesoil-pipe memher and the vent-pipe; a lateral drainage-dischargearranged to discharge into the vent and drainage duct; and an inclineddeflector arrangedinside of the drainage and vent duct above and overthe lateral drainage-discharge to direct the water downwardly.

5. A drainage and venting pipe provided in its length with anenlargement; a lateral drainage-receiving opening or openings in theenlargement; and inclined deflectors projecting out from the wall of theenlargement over such openings, the lower ends of said deflectorsextending out beyond the inner wall of the pipe, whereby the incomingstream has a free outlet and is directed downwardly into the pipe,substantially as described.
